FILTERBANKTIGHT Tight filterbank
Usage: gt=filterbanktight(g,a,L);
gt=filterbanktight(g,a);
FILTERBANKTIGHT(g,a,L) computes the canonical tight filters of g
for a channel subsampling rate of a (hop-size) and a system length L.
L must be compatible with subsampling rate a as
L==filterbanklength(L,a).
FILTERBANKTIGHT(g,a,L) does the same, but the filters must be FIR
filters, as the transform length is unspecified. L will be set to
next suitable length equal or bigger than the longest impulse response.
The input and output format of the filters g are described in the
help of FILTERBANK.
REMARK: The resulting system is tight for length L. In some cases,
using tight system calculated for shorter L might work but check the
reconstruction error.
